This means that a negative angle represents a rotation in the opposite direction from the positive angle with the same magnitude. TrigonometryMath
Since arctan is the inverse of the tangent function, and many angles share the same tangent value, arctan is a periodic function. Each arctan value can result in multiple angle values, which is why the range is restricted to [-π/2, π/2]. To calculate arctan, use a scientific ca...

a sin calculator is to evaluate sin expressions that you provide. The are some notable angles, usually multiples or fractions of \(\pi\) that are simple, integer or fraction results when calculating their sin, so it is a good idea to use a sin expression calculator to help you with that...
if the circle is divided by the corresponding central angles, then the area of the red part is $\frac{144}{360}=40\%$ of whole. Conversely, in order to find the measure of the central angle, we have to find the percent represented by the piece, then multiply $360^o$ by the perce...
Since this equation is quadratic for T, there can be both a positive and a negative solution. However, we are concerned only with positive solutions, since only positive distance makes sense. 1. Select the Solve aplet and enter the equation. Select Solve X V T A T2 2. Find the ...
Can an ellipsoid have negative volume? No, an ellipsoid cannot have a negative volume. The lengths of the semi-major axes (A, B, and C) are always positive values, so the calculated volume is always positive. What is the ellipsoid volume if the semi-axes are 3cm, 6cm, 8cm? The ellip...
🙋 Having trouble finding central angles? Perhaps ourcentral angle calculatorcan help you with that. Using this haversine distance formula,you can translate latitude and longitude to distance, given the coordinates of two points on Earth, although with a minor setback. It can result in an error...
